plates: section of the lithospere that slowly moves over the ansthenosphere , carrying pieces of continental and oceanic crust
scientific theory: well-tested concept that explains a wide range of observations
plate tectonics: theory that pieces of Earth's lithospere are in constant motion, driven by convection currents in the mantle
fault: break in Earth's crust where slabs of rock slip past each other
transform boundary: plate boundary where two plates move past each other in opposite directions
divergent boundary: plate boundary where two plates move away from each other
rift valley: deep valley that forms where two plates move apart
convergent boundary: plat boundary where two plates move towards each other
Outline
A Theory Of Plate Motion:
Combine known facts of sea-floor spreading with unknown facts
Lithosphere on top of ansthenosphere
Flow of currents= moving of Earth's plate
Plate Boundaries:
Three different types: transform, divergent, & convergent
Transform Boundary: Plates slip past each other
Divergent Boundary: Plates slip apart
Convergent Boundary: Plates collide
The Continents' Slow Dance:
Plates move slowly=1-10 cm. per year
Plates moving= tens of million of years
Pangea was born that time
